APPARATUS FOR PURIFYING WATER.

. To' all wiz/07% it may concern:-

Be it known that we, SOLOMON L. SHEER- MANl and JUAN F. HAND, citizens of the United States of America, and residents of Des Moines, in the county of Polk and'State of Iowa, have invented certain new and usefullmprovements in or Relating to A paratus for Purifying Vatenof which the ollowing is a speciiication.

The invention hasfor its obj ect to remove automatically from feed-water for steamboilers or the like such matters as may produce sediment or incrustation, to 'prevent said matters entering the boilers, and to admitonly pure water, and involves automatic means for the addition to and the mixing with the -Water of certain namedingredients, such as lime and soda.

The apparatus to which this application is directed 1s one intended to secure the accurate addition to-and thorough intermingling with thewater of'these ingredients and is applicable where crude or natural water is used for feeding. v

The purifying rocess consists in adding a suitable chemicalpsolution or reagent for any special kind of water, and in cases where the reagent is apt to cause a sediment if not stirred up provision is made for maintaining the same in a perfect and constant solution.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar reference-numerals designate corresponding parts in all the views.

Figure 1 is a longitudinal sectional elevation of the complete apparatus with a part of the reagent-'container broken away to illustrate the means for discharging a quantity of the chemical solution into the mixingchambers. Fig. 2 is a longitudinal sectional elevation of the reagent-container." Fig. 3 is a planof the complete apparatus. Fig. 4 is a detail view of the valve-operating parts.'

Referring to the drawings, the apparatus consists of a container 10 for the reagent.

This container is provided with gutters or troughs 11 and 12 and buckets 13 and 14, pivoted to the u per ends of the gutters, the bucket 13 disc arging into the gutter 1.2 and thence to a chamber 1.5 and the bucket 14 discharging into a gutter 11 `and `thence to a chamber 16. I

The natural or crude water to be treated is led direct through an inlet-pipev 17 into the Specification. of Letters Patent. Application tiled May 20, 1905. Serial No. 261,410.

oscillating receiver 18 and when this receiver is partially filled the .center .of gravity is moved and the receiver oscillated in such manner as to our'out its contents into one or the other o the chambers 15 or 16. Y

The receiver 18 is mounted and articulates on a shaft 1.9, having suitable bearings fixed to the sides of the Achambers 15 and 16. Near each end of the receiver is a dam 20 to retain a quantity of water there for purposes hereinafter made clear. Y

That end of the receiver 18 which disone end and to a vertically-.movable rod 22,v

fixed to the side of the container 10, and a chain 23, fixed to the top of the rod 22 and to the outer end of the bucket 1,3, the' contents of which-is dischargedinto the gutter 12 and thence to the chamber 15.

A float 24 is arranged in the chambery 15 and is provided with a tubular extension 25, 'i

which Vembraces a guide-rod 26, secured to the bottomof the chamber 15. As the Water in the chamber rises the tubular extension of the float engages and lifts the one end i of the oscillating receiver, thus stopping the flowof Water into the chamber 15 and directby means of a rod 34. As the oscillating receiver moves to discharge into onel or the other of the chambers 15 or 16 the levers 3 1'j and 32 are o erated to open andclose the -valves 29 an 30, and the water that is retainedV in the receiver 18 by the dams 20 is causedk to flow in a body over to the side Where the valve is to be closed and by its weight hold the valve against the mouth of the outlet-pi e,and thus prevent the escape of water.

parteA to close one of the valves similarrdevices are arranged to open the other valve. n h

To maintain the reagent in the container imultaneously Withthe operaies 10 in a perfect and constant solution, an Y agitator 35 is provided and is moved longitudinally of the container with each operation of the oscillating receiver 18.

The iioat in the chamber 16 is the counterpart of the iioat 24 in the chamber l5 and is to perform the same function and operate in the same manner.

In practical use water is supplied to the oscillating receiver 18 through the inlet-pipe 17, which when it is partially filled oscillates in one direction and closes the valve 29 in the chamber 15, at the same time opening the valve 30 in the chamber 16. The agitator 35 is then moved in the container 10 and the bucket 13 caused to discharge a quantity of the reagent into the chamber 15. As the flow of water continues into the chamber 15 the fioat 24 rises, the tubular extension 25 of which engages and lifts the oscillating receiver to a position over centen thus directing the water to flow into the chamber 16, the arrangement of the lever 31 for vclosing the valve 30 being such as to cause said valve to be seated before the contents of the receiver is discharged into the chamber 16, and the water in said receiver, retained therein by the darn 20 at the opposite end, is directed in a body to flow over to and be retained by a second dam 20 to lend such weight to the oscillating receiver as will assure the perfect seating of the valve 30.

The operation is continuous, and so long as water is directed to the oscillating receiver the reagent is automatically discharged into one or the other of the chambers, the agita tor in the reagent-container is moved, and the valves in the mixing-chamber are operated to open or close.

Having thus described our invention, what we claim as new therein, and desire to secure py Letters Patent of the United States thereor, lsn 1. An apparatus for purifying water embodying a reagent-container, a pair of tanks therebeneath, an oscillating receiver, a pair of oppositely-inclined stationary gutters leading from said container to said tank, a bucket pivoted to the top of each container, and a connection between each end of said receiver and the adjacent bucket.

2. An apparatus for purifying water embodying a reagent-container, a pair of tanks beneath, and an oscillating receiver, a pair of oppositely-inclined stationa gutters leading from said container to said tank, a bucket pivoted to the top of each gutter, vertically-movable rods, flexible connections between said rods and said buckets, and second rods pivoted to said first-named rods and said receiver.

3. An apparatus for purifying water, embodying a reagent-container, a pair of tanks therebeneath, an oscillating receiver, a gutter leading from said container to each of the tanks, means for elevating a quantity of said reagent into said gutters, agitating means in the container movable in a horizontal plane and sliding on the bottom of said reagentcontainer, and connections between each of said elevating means and said agitator whereby when said receiver is operated said elevating means will be oppositely operated in unison and said agitating means will be given movement simultaneously therewith.

4. In an apparatus for purifying water, a pair of tanks, an oscillatingr receiver, an outlet-pipe for each tank, a pair of pivoted levers engaged by the bottom of the tank, a valve for each outlet, and rods connecting said levers and valves.

5.

'7. An apparatus for purifying water, embodying a pair of tanks, an oscillating receiver, a reagent-container, an agitator for said container sliding horizontally on the bottom thereof, and a rod having its intermediate portion relatively stationary with respect to the container receiving movable support therefrom, and having its ends connected to said agitator and said receiver.

8. An apparatus for purifying water, embodying a reagent-container, a pair of tanks therebeneath, a receiver, a pair of oppositelydisposed inclined gutters in said container leading into said tanks, a bucket pivoted at one end to each gutter, vertically-movable rods connected to the opposite ends of the buckets, and means for operating said rods from said receiver.
